Answer:
Step-by-step explanation:
To find the number of inches, divide miles by 9.5.
__
a) 24 miles = (24 mi)×(1 in)/(9.5 mi) = (24/9.5) in ≈ 2.526 in
__
b) 24 miles + 16 miles = 40 miles = (40 mi)×(1 in)/(9.5 mi) = 40/9.5 in ≈ 4.211 in

Comment on units conversion
I find it convenient to work units conversion problems by writing a fraction that is equal to 1 and multiplying by that to change units. My fraction has the "to" units in the numerator, and the "from" units in the denominator. That way, the unwanted units cancel when the multiplication is carried out.
The fraction is equal to 1 because the measurement in the numerator is equal to the measurement in the denominator.
__
Some folks prefer proportions. If you do it that way, be sure "like" is matched with "like".
map inches/ground miles = 1/9.5 = x/24
route inches/scale inches = route miles/scale miles = x/1 = 24/9.5
The probability would be 2/11 because there are two markers that are purple and gray. Also, there are 11 markers. So my final answer is 2/11.
Answer:
Absolute value equation is; |x - 25| ≤ 3
Minimum number of bolts is 22 while Maximum number of bolts is 28
Step-by-step explanation:
We are told that;
Each bag should have 25 bolts in it but 22 or 28 is acceptable.
Since 22 or 28 is acceptable, it means the allowable error is ±3.
Thus, if x is the number of bolts in the bag, the absolute value equation would be;
|x - 25| ≤ 3
Minimum number of bolts is 22 while maximum is 28
Answer:
slope of 2y- 5X = -20: m=
Convert to standard form: 5x- 2y=20
Slope using standard form: m=5/2
slope - Intercept form of 2y-5x= -20:
y=mx+b
y=5/2x-10
Axis interception points of 5/2x-10:
X Intercepts: (4, 0),
Y Intercepts: (0, - 10)
Could you please provide the equation and the rest of the question?
